摘要： Disclosed is a driving circuit and method for a fluorescent lamp. The driving circuit comprises a power factor correction (PFC) stage, a startup stage, an isolation stage, a square-wave driving stage and an output stage. The PFC stage receives and converts an input alternating current (AC) voltage into a direct current (DC) voltage. The startup stage receives the DC voltage and adjusts the DC voltage into an operating voltage. The startup stage is connected in parallel with the square-wave driving stage. The square-wave driving stage is connected to the isolation stage and converts the operating voltage into a boosted square-wave voltage, and the output stage receives the boosted square-wave voltage to ignite the fluorescent lamp. As such, the fluorescent lamp may be rapidly and properly ignited.

摘要： A startup method for a mercury-free flat-fluorescent lamp is provided, which comprises providing a train of voltage pulses for driving the lamp; and changing the duty circle, switching frequency, and/or operation voltage level of the driven voltage pulse during the startup period of the lamp. The above factors are properly combined to achieve the rapid ignition, the uniform light up, and the lower startup current.
